After every maintenance, lag of Cyrodiil at EU server gets even worse. And during game play, bugs like "stuck in combat" and enemy ball groups take all the fun out of this game.
ZOS is not doing anything about the lag, although there are hundreds of complaints. And with every patch, they are making it easier for ball groups. Many old bugs are still unresolved.
So that's it, I quit this game that got me really excited once. I'm playing games to relax, not to stress because of never ending technical problems, bugs, and wrong game mechanics.
Good luck to to those who stay...
